Sandipan Das 73e1f48e51 perf vendor events amd: Fix Zen 5 MAB allocation events 
[ Upstream commit 76b2cf07a6 ]

The unit masks for PMCx041 vary across different generations of Zen
processors.

Fix the Zen 5 events based on PMCx041 as they incorrectly use the same
unit masks as that of Zen 4.

Fixes: 45c072f253 ("perf vendor events amd: Add Zen 5 core events")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
